CAN-CLOSING? MeoHIivn.

Application filed August 3, 1822. Serial No; 579,329.

To all whom it may concern:

Be it known that 1, ROBERT FLANroAN, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Canlllosing Machines, of which thefollowing is a specification.

v This invention relates to improvements in can closing machines, and is adapted for closing either double or slngle seamed can heads.

The invention consists of the. novel con-r struction and arrangement of the parts and combination of parts hereinafter more fully set forth in the following specifications and pointed out in detail in the appended claims. I

In the accompanying drawings,- Figure 1 is a side elevation, partly in section, of a can closing machine having my invention applied thereto, and showing a can in position to be sealed,

Figure 2 is a detail vertical longitudinal section, on an enlarged scale, of the closing tool.

Figure 3 is a detailloottom view, on an enlarged scale, of the closing tool.

Figure 4 is a View similar to Figure 8,"but showing a modified form of'closing tool.

Figure 5 is a detail plan View of the mod1- fied form of the tool member.

Figure 6 is a detail elevation of the plunger shown in Figure 1.

Referring to the accompanying drawings, forming part of this specification, and m which like reference numbers designate like parts throughout the several views thereof, 1 designates a closing machine having pulleys 2 and 3 revolubly mounted at one side thereof. The pulley 2 is driven by a belt (not shown) which receives its power from the main power shaft, or other source of power. The said pulleys 2 and 3 are keyed together and revolve in unison. A belt (not shown) passes from the pulley 3 over the idler 4 to the pulley 5 which latter is fast on the hollow shaft 6'. The said hollow shaft 6 is revolubly mounted in the bearings 7 and 8 of the machine 1 and carries a toiol comprising a head 9 which is secured to the lower end of the hollow shaft 6 in any suitable manner. Extending through the head 9 and adapted to be reciprocated therein, is

a closing tool member 10 having a washer P 11 to limit the movement of said tool memher, said washer being held position by the screw 12. the tool member 10 is a short vertical shaft 13 having a head 14: on one, end and a nut 15 threaded on its upper end; A set screw 16 projects throughthe outer end of the tool member 10 and has its inner end i impinging against the shaft 13 to hold the latter in theyadjusted position in the slot T0. 011 the lower end of the short shaft 13 is revolubly mounted aspinning wheel 17 having a groovelSwhich ole-operates with the flange 19 on the ring 20, which latteris revoluhly mounted on the lower end of the head '9 and is held thereto by the screw 21.

' Within the hollow shaft dis a vertically re cip'rocating plunger22 having a threaded aperture 23 in its upper end into which the screw 24;, adjustably fitted. The said screw 24: has a head 25 and an apertured boss 26 above said head and is held to the adjusted position in theplunger 22 by the nut 27; The said boss 26 is pivoted to the lever 28 which latter is inturn pivoted to the bracket 29 on the frame 1. The said'lever 28 is i adapted to forcethe plunger 22 down to cooperate with the tool member 10, the said plunger 2 2 being raised and held in its normal pos tion by the coiled spring 30. This coiled spring 30 permits the plunger 22 to yield in case there is too great pressure against the tool member 10 when the tool is in operation. The lower end of the plung- Inlthe outer end of 33, having a. shaft 34 which projects through the lower end of the said frame 1 and is pivoted to and operated by the treadle 35. Said rest being held to its normal position by the coiled spring 36.

In Figures 4 and 5 I have shown fication of the closing tool member 37. In

this instance two spinning wheels 38 and 39 are employed, the one 38 being revolubly mounted at the outer endof the tool member 37 and the other 39 being revolubly mounted on the integral arm 41. The wheel 39 belng adapted to come into contact with.

the can head slightly in advance'of' the wheelr38. and as the tool member 37 moves inwardly the wheel 38'comes into contact with the partly spun seam and finally the l W l .what I claim is:

wheel 39 is out of contact With the seam and the Wheel completes the closin While I have shown the plunger 22 with a cone-shaped lower end to (lo-operate with the cone-shaped aperture in the tool members 10 and 3'? to force the latter back in the head 9, it is obvious the shape of the end of the plunger 22 as Well as the aperture in the tool members 10 and 37, may be varied to accomplish the same object.

Having thus described my invention,

1. A can closing tool comprising a head, a ring revolubly mounted on one end of said head, a tool member adapted to be reciprocated in said head, and a spinning Wheel carried by said tool member and adapted to co-operate with said ring to close the can seam, and a plunger operating Within the head on said tool member.

.2. A can closing tool comprising a head,

a ring revolubly mounted on one end of 4. A can closing tool comprising a head, atool member adapted :to be reciprocated in said head, and two spinning Wheels operating in succession carried by said tool member in the same plane at one end thereol andadapted to co-operate with the said head to close the can seam. I

5. A can closing tool comprising a head, a tool member adapted to be reciprocated in said head, a ring revolubly mounted on one end of said head, a spinning wheel carried by, said tool member, and a plunger projecting into said head and adapted to reciprocate said tool.

6. A can closing tool comprising a head, a tool member adapted to be reciprocated in said head, a ring revolubly mounted'on one end of said'head, a spinning Wheel carried by said tool member and adapted to co-opcrate with said ring, and a reciprocating plunger projecting into said head and adapted to reciprocate said tool member.

7. A can closing tool comprising a head, a ring revolubly mounted on one end of said head, a tool member adapted to be reciprocated in said head, a spinning Wheel carried by said tool member and adapted to co-operate with said ring to close the can seam, a plunger operating Within the said head on said tool member, and a spring at the upper end of the said plunger to return it to its normal position.

In testimony whereof I fllfiX my signature.

ROBERT FLANIGAN.
